IPROVED MODE QI' SECURING QARIAG-E-WHEELS .ON THEIR AXLES.

The 'Schedule referred to in these Letters Patent'and making part of the same To all who-m it may concern:

' Beit known that I, IRA BICKNELL, of Cincinnati, in the county of Hamilton in the State of Ohio, haveinvented a new, useful, and improved Mode of Preventing Wagon or Carriage-Wheels from Coming O iIr from the Axle; and I do hereby declare that the follow-l ing is a full and exact description thereof', reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in providing or making a screw upon a wagon or carriage-axle, ncar its shoulder, and a corresponding nut or screw in box oi' wheel; also, a capot' piece of metal, provided with a set-screw at point or outer end of axle; all of which is to prevent the wheel coming oi` from the axle.

To enableothers skilled iu the art to make and use my invention, I will proceed to describe its construction and operation.'

I construct my wagon or carriage-axles and boxer hub for same in any of the known forms, and apply thereto nuts, linch-pins, and the other appendages of such axles and boxes; but, in order to obviate the danger or possibility ot' the wheel coming oi from the axle by loss or absence of nut, linch-pin, or other fastening at outer, end of axle, I make or place a screw around the axle, near its shoulder, as shownlatA i-nl accompanying drawings; and to fit this screw, I make a corresponding nut or screw in the inside of the box of the hub of wheel, as shown at B in drawings.

I make also, adjoining the nut, a recess or groove, O, in the inside ot' box of suiiicent-width toreceive the screw A, on the axle, after it has passed the nut B.

The axle and box are put together by inserting the end ofthe axle in thel box of the hub' of wheel, and turning the wheel around unt-il the nut B, inside the box,lias passed entirely over the screw A on the axle, andthe' said 'screw' A rests in the groove O in the box, and the screw Bin the box-.occupies the space between the screw A and the shoulder of the axle, when the wheel is free to revolve, and cannot be taken ott" except by reversing the movement by which it was placed upon the axle. l

I do not. confine myself to any specific number of threads .or number oi' times to be passed around the axle, but in general I make the screw of one thread passing twice around the axle, and a corresponding vone in 'the box, which makes it necessary' for the wheel to be turned backward two complete revolutions bcfore it can come oi or be taken olf from axle, and this screw on axle I make a leit'or right-handed one, according to the revolution required of wheel when in use; that is, I inakejt alight-handed one, when thc wheel is to turn v'co the right, and a left-handed one, when the wheel is toturn to the left; also,as"dditional security to be used in connection with atorcdescribed screw or separately therefrom, l make, in' outer end ot' axle and nut E on same, a slot or groove', D, at right angles to the axle, and itto same 'a cap or piece of metal, F, with a' tongue, G, litt-ing s aid slot or groove D, said cap or piece of metal being secured to its place by screw H inserted vthrough it into the end ofthe axle, as shown.

This tongued plate and screw serve to render it almost impossible for the nut to runA oil the axle-.by either friction or jar. y

I claim herein as new and of my invention- 1. In the described combination with'the recess O `and the screw-threaded end-'B ot vthe box, the screwthreaded collar A of the axle, for the` purpose specified;

2. The groove D int-he nut E, and upon the end ofa the axle, the plate or collar F, having the tongue formed thereonand screw H, combined and arranged in the manner and for tlie purpose specified.

In testimony of which invention I hereunto set my O. F. SHEPARD.
